Social media posts mistakenly link hormonal birth control to polycystic ovary syndrome, infertility and depression
Hormonal birth control has been linked to “PCOS”. [polycystic ovarian syndrome]hormonal imbalances, depression and infertility”
Factually inaccurate: Several studies show that hormonal contraceptives do not affect fertility. Rather than causing polycystic ovary syndrome (PCOS), hormonal birth control pills help control PCOS symptoms and reduce long-term risks.
Insufficient support: Studies examining a possible association between hormonal birth control and the risk of depression have provided conflicting results and are inconclusive due to conflicting results.
TAKE THE KEY WITH YOU
Hormonal contraceptives are an effective way to prevent pregnancy. In addition to contraception, they can also be used to regulate periods, prevent excessive menstrual bleeding, improve acne or treat polycystic ovary syndrome (PCOS). Contrary to claims on social media, such contraceptives have not been linked to harmful effects on women.
FULL CLAIM: “An entire generation of women was prescribed birth control for acne and irregular periods from the age of 14, and now that same generation is dealing with PCOS [polycystic ovarian syndrome]hormonal imbalances, depression and infertility”
Birth control (contraception) refers to any method, drug, or device used to prevent pregnancy. Common methods include permanent male and female sterilization, barrier methods that block sperm, such as condoms and diaphragms, and hormonal methods.
All hormonal birth control pills contain a synthetic form of the female hormone progesterone, alone or in combination with another female hormone called estrogen. These hormones prevent pregnancy by inhibiting the release of an egg (ovulation), thickening the mucus around the cervix to prevent sperm from entering and fertilizing the egg, and/or thinning the lining of the uterine wall to prevent a fertilized one to prevent ovum from attaching to it.
However, hormonal contraceptives also have other uses unrelated to birth control. For example, they can help control irregular periods, excessive menstrual bleeding, and acne. They can also relieve premenstrual syndrome, a combination of physical and emotional symptoms of varying intensity that most women experience a week or two before their period and, in some cases, can be temporarily debilitating.
In April 2022, a Facebook post suggesting that these non-contraceptive uses have harmful effects went viral on the platform, garnering more than 86,000 shares. The post reproduced a tweet from a video blogger known as Reallygraceful who specifically linked the use of hormonal contraceptives during adolescence to the development of polycystic ovary syndrome (PCOS), hormonal imbalances, depression and infertility later in life.
The tweet went viral in February 2022, prompting some gynecologists to refute the claims on social media, stating that birth control pills do not cause or contribute to PCOS or infertility. This was documented in a podcast (timestamp 5:31) that Reallygraceful released on their YouTube channel, which has amassed over 360,000 subscribers and allegedly provides evidence to support their claims.
However, the podcast didn’t cite any scientific studies, instead collecting anecdotal accounts from some women, including Reallygraceful herself, about the supposedly harmful effects of birth control. Given that anecdotal evidence tends to be biased for a variety of reasons, such as B. the fallibility of human memory and confirmation bias, they are unreliable without systematically collected and analyzed scientific data to support.
Several studies show that long-term use of hormonal contraceptives does not affect fertility
The claim that birth control causes infertility is a pervasive myth that is unsupported by scientific evidence, as gynecologist Jennifer Gunter explains on her blog, The Vajenda. Research shows that hormonal birth control does not affect fertility. About 20% of women become pregnant within their first cycle after stopping hormonal birth control, and most of them can become pregnant within the first year[1,2].
A 2018 systematic review and analysis of 22 previous studies found no difference in fertility rates between women who stopped birth control after using intrauterine devices (IUDs) and women who used hormonal birth control pills, including implants, injections and pills had.
Another study published in the British Medical Journal in 2020 the ability to conceive in nearly 18,000 women from Denmark, Canada and the US after stopping hormonal birth control, IUDs and barrier or natural birth control methods between 2007 and 2019. While the authors found that some hormonal birth control methods caused a slight delay in return to fertility compared to barrier and natural methods, conception rates at one year were similar among the different groups. The authors concluded that long-term use of these methods had “little or no lasting effect” on fertility.
Hormonal birth control pills are not associated with PCOS but are instead part of treatment
PCOS is a hormonal disorder that affects the functioning of the female ovaries. Symptoms include irregular menstrual periods and abnormally high levels of male sex hormones (androgens), which are usually present in small amounts in women. Sometimes the ovaries also enlarge due to the accumulation of unreleased eggs in the form of multiple small, fluid-filled follicles.
According to the US Centers for Disease Control and Prevention (CDC), PCOS affects an estimated 6 to 12% of women of childbearing age in the USA and is one of the most common causes of female infertility. In addition, this condition also increases the risk of metabolic problems such as diabetes, as well as heart disease, blood clotting and stroke. PCOS has no cure, but diet and activity changes and medications help manage symptoms and prevent these long-term complications.
Although the exact cause of PCOS is unknown, several factors such as family history, higher androgen levels, and obesity are suspected. In a blog post, Jennifer Gunter explained that current epidemiological evidence does not suggest that hormonal contraceptives are among these factors. On the contrary, combined hormonal contraceptives are often part of long-term PCOS treatment for women who do not want to have children because they help regulate menstruation and lower androgen levels.
Like any medical procedure, hormonal contraceptives can cause side effects, most of them minor. Common side effects include nausea, headaches, breast tenderness, and spotting or bleeding between periods. Serious side effects, including high blood pressure, blood clots, heart attacks and strokes, have been reported but are very rare, Health Feedback explained in a previous review.
There is consistent evidence that hormonal birth control is also associated with a slightly higher risk of breast and cervical cancer. On the other hand, hormonal contraceptives reduce the overall cancer risk by providing significant protection against colon, ovarian and endometrial cancer[4,5]. Therefore, birth control pills could offer an important benefit for women with PCOS, who are at higher risk of endometrial cancer.
Studies linking hormonal birth control during adolescence to an increased risk of depression have provided conflicting results and are therefore inconclusive
Reallygraceful’s claim that hormonal birth control causes depression may be based on a study published in JAMA Psychiatry in 2016, which assessed the risk of depression in more than one million women in Denmark. The study found that teenage girls who used hormonal birth control were about twice as likely to develop depression than those who never used hormonal birth control.
However, these results only showed an association between hormonal contraception and depression. This does not mean that hormonal contraceptives cause depression, as association alone is not evidence of causality.
Overall, research evaluating the potential effect of hormonal contraceptives on the risk of depression has produced conflicting results. A recent review in the Journal of American Psychiatry in 2021 concluded that “clinical trials and randomized placebo-controlled trials in women with psychiatric disorders have generally reported similar or lower rates of mood symptoms in hormonal contraceptive users compared to non-users.”. However, more research is needed to draw more definitive conclusions.
Social media posts linking hormonal contraceptives to PCOS, infertility and depression are based on anecdotal evidence that contradicts the scientific data currently available. Several studies show that hormonal contraceptives do not cause infertility. Also, there is no evidence of a link between the development of PCOS and prior use of hormonal contraceptives, which are actually effective in relieving PCOS symptoms. Evidence for an association between hormonal contraceptives and depression is inconclusive.
